Abstract

PROBLEM TO BE SOLVED: To reduce the thickness of a projection type capacitive touch panel.SOLUTION: In a projection type capacitive touch panel 2, electrodes 11(a) and (b) are patterned on a film 12, not on a reinforcement screen 90. Therefore, the projection type capacitive touch panel 2 is manufactured through a process in which the film 12 with the electrodes 11(a) and (b) patterned thereon is adhered to the reinforcement screen 90. This allows the touch panel to use as the reinforcement screen 90 a screen obtained by dividing a large screen into pieces and then being subjected to reinforcement processing on its whole surface. In the projection type capacitive touch panel 2, the electrodes 11 are pattered on the back surface of the film 12, and a member for protecting the electrodes 11 from heat from a display device 70 is used as a protective layer 87. This eliminates the need of a transparent substrate 81. Consequently, the thickness of the projection type capacitive touch panel 2 can be reduced.

Description

  The present invention relates to a projected capacitive touch panel.

  In recent years, operations (selection, etc.) of various information displayed on a display device can be performed on a mobile phone, a PDA (Personal Digital Assistants), or an electronic device such as a portable game by bringing a finger or the like closer. There is something that can be done with a projected capacitive touch panel.

  In an electronic device using a projected capacitive touch panel, a change in capacitance generated between an electrode provided on the projected capacitive touch panel and a dielectric finger or the like is detected, and the change is detected. The position of the formed electrode is specified as coordinates. In the electronic device described above, the information displayed on the display device is switched, for example, on the assumption that various types of information located at the specified coordinates are operated (selected or the like). As described above, since the projected capacitive touch panel serves as a sensor for specifying coordinates where a finger or the like is approaching, it is important to stably detect a change in capacitance.

  For this reason, in Patent Document 1, when the electrodes are constituted by column electrodes extending in two directions orthogonal to each other (a column electrode extending in one direction and a column electrode extending in the other direction), an insulating layer is formed at a position where the column electrodes intersect each other. A projection capacitive touch panel that prevents short circuit between column electrodes and can stably detect a change in capacitance has been proposed.

  When a projected capacitive touch panel device integrated with a display device is manufactured using the projected capacitive touch panel described in Patent Document 1 described above, the structure of the projected capacitive touch panel is complicated. Therefore, there is a problem that it is difficult to reduce the thickness.

  This problem will be described in detail with reference to FIG. 2 and FIG. First, the external appearance of the projected capacitive touch panel device 100 using the projected capacitive touch panel described in Patent Document 1 will be described with reference to FIG.

  The projected capacitive touch panel device 100 includes an electrode 82, a flexible substrate 85, a touch panel driver IC (Integrated Circuit) 86, a screen decoration 88, and a reinforced screen 90 as a configuration that can be visually recognized from the appearance. Yes.

  The electrode 82, when a dielectric finger or the like approaches, generates a capacitance between the finger and the like, and ensures the visibility used for identification by the touch panel driver IC 86 at the position where the finger or the like approaches. It is a transparent electrode. The electrode 82 is made of ITO (Indium Tin Oxide) and is made up of column electrodes 82 (a) and (b) extending in two directions intersecting each other. Specifically, the electrode 82 includes a plurality of column electrodes in which column electrodes 82 (a) extending in the vertical direction (one direction) and column electrodes 82 (b) extending in the left and right direction (the other direction) are arranged in a matrix. 82 (a) and (b).

  The flexible substrate 85 is a flexible substrate on which a touch panel driver IC 86 and resistors necessary for the operation of the touch panel driver IC 86 are mounted.

  The touch panel driver IC 86 detects a change in capacitance generated between the dielectric (such as a finger) and the electrode 82, and specifies the position of the electrode where the change is detected as coordinates.

  The screen decoration 88 decorates the reinforced screen 90 and is formed on the back surface (the surface opposite to the viewing side) of the reinforced screen 90 by printing.

  The reinforced screen 90 protects devices and the like (a display device 70 and the like described later) in the projected capacitive touch panel device 100 from external pressure generated by contact with a finger and the like, and various information displayed on the display device 70. It is a screen that secures the visibility. The reinforced screen 90 is subjected to a process for increasing the strength against external pressure over the entire surface.

  An example of the internal configuration of the projected capacitive touch panel device 100 will be described with reference to the cross-sectional view of FIG. 3A is a view of a cross section taken along the line ff (see FIG. 2) of the projection capacitive touch panel device 100 as viewed in the direction of the arrow.

  The projected capacitive touch panel device 100 includes a display device 70, a capacitive touch panel 80 disposed on the upper side (viewing side), and a reinforcing screen 90 disposed on the upper side (viewing side). ing. In the following description, components having the same reference numerals as those in FIG. 2 have the same configurations as those described in FIG. A combination of the capacitive touch panel 80 and the reinforced screen 90 is a projection capacitive touch panel 60.

  The display device 70 is a display device using a liquid crystal display or an organic EL display for displaying various information. The capacitive touch panel 80 is a panel that ensures visibility, and plays a role of a sensor for specifying coordinates at which a dielectric finger or the like approaches.

  The capacitive touch panel 80 includes a transparent substrate 81, an electrode 82, an insulating layer 83, a wiring 84, a flexible substrate 85, a touch panel driver IC 86, a protective layer 87, a screen decoration 88, an adhesive layer 89, It has.

  The transparent substrate 81 serves as a base on which the electrode 82 (b), the insulating layer 83, and the wiring 84 are formed, and protects the electrode 82 from heat radiation by the display device 70. As described above, the electrode 82 is an electrode that ensures visibility, and the column electrode 82 (a) extending in one direction (vertical direction) and the column electrode 82 (b) extending in the other (left and right direction) are combined with an insulating layer. It is formed as an electrode having a two-layer structure insulated at 83.

  The insulating layer 83 is a layer that ensures the visibility of the column electrodes 82 (a) and (b) in an insulated state. The wiring 84 is a metal printed wiring and is independently connected to each of the column electrodes 82 (a) and (b).

  2A shows the wiring 84 connected to the column electrode 82 (a) extending in one direction among the column electrodes 82 (a) and (b), and the column electrode extending in the other direction. The wiring 84 connected to 82 (b) is not shown. Since the visibility of the wiring 84 is not ensured, the wiring 84 is hidden by a screen decoration 88 so that the wiring 84 cannot be visually recognized through the reinforcing screen 90.

  The protective layer 87 protects the electrode 82 while ensuring the visibility of various information displayed on the display device 70.

  Such a projected capacitive touch panel device 100 is required to be as thin as possible with the thinning of mobile phones and PDAs. In this thinning, particularly in the case of a set manufacturer that purchases and uses the display device 70 from another company, it is difficult to reduce the thickness of the display device 70. Therefore, the thickness h1 of the capacitive touch panel 80 becomes a problem. And the thickness h2 of the reinforced screen 90, that is, the thickness of the projected capacitive touch panel 60.

  As one configuration example for solving this problem, there is a projected capacitive touch panel device 200 shown in FIG. The projected capacitive touch panel device 200 has a structure that eliminates the need for the transparent substrate 81 and the adhesive layer 89 used in the projected capacitive touch panel device 100. FIG. 3B is a cross-sectional view taken along the arrow ff (see FIG. 2) of the projected capacitive touch panel device 200 in the arrow direction.

  The projected capacitive touch panel device 200 includes a display device 70, a capacitive touch panel 180 disposed on the upper side (viewing side), and a reinforcing screen 190 disposed on the upper side (viewing side). ing.

  In the following description, components having the same reference numerals as those in FIG. 3A have the same configurations as those described for the projected capacitive touch panel device 100, and thus description thereof is omitted. A combination of the capacitive touch panel 80 and the reinforced screen 90 is a projection capacitive touch panel 160.

  The capacitive touch panel 180 includes an electrode 182, an insulating layer 183, a wiring 84, a flexible substrate 85, a touch panel driver IC 86, a protective layer 87, and a screen decoration 88.

  When a dielectric finger or the like approaches, the electrode 182 generates a capacitance between the electrode and the finger, and is used for identification by the touch panel driver IC 86 at a position where the finger or the like approaches. This electrode 182 is a transparent electrode that ensures visibility by patterning ITO on the back surface (the surface opposite to the viewing side) of the reinforced screen 190.

  Similarly to the electrode 82 shown in FIG. 3A, the electrode 182 includes a column electrode 182 (a) extending in one direction (vertical direction) and a column electrode 182 (b) extending in the other direction (horizontal direction). ing. On the other hand, the electrode 182 is different from the electrode 82 shown in FIG. 3A in that an insulating layer 183 is provided only at a position where the column electrodes 182 (a) and (b) intersect with each other, thereby providing the column electrode 182 (a ), (B) are in an insulated state.

  In this way, the electrode 182 is patterned directly on the reinforcing screen 190. Therefore, the capacitive touch panel 180 can eliminate the adhesive layer 89 used in the capacitive touch panel 80. Therefore, the capacitive touch panel 180 realizes a reduction in thickness h2 as compared with the capacitive touch panel 80.

  In addition, the capacitive touch panel 180 is provided with an insulating layer 183 only at a location where the column electrodes (a) and (b) intersect. Thereby, the protective layer 87 can be provided in an open space (a space where the insulating layer 83 is necessary in the capacitive touch panel 80). This protective layer 87 can be used as a member for protecting the electrode 182 from heat dissipation by the display device 70. Therefore, the capacitive touch panel 180 can eliminate the need for the transparent substrate 81 used in the capacitive touch panel 80. Therefore, the capacitive touch panel 180 realizes further thickness reduction in the thickness h2 as compared with the capacitive touch panel 80.

  However, in the projected capacitive touch panel device 200 (see FIG. 3B), the electrode 182 is patterned directly on the reinforcing screen 190. For this reason, the assembly process of the capacitive touch panel 180 and the reinforced screen 190 is as follows.

  That is, first, a large screen is subjected to a strengthening process to obtain a strengthened screen 190. Next, the electrode 182 is patterned on the reinforcing screen 190. Finally, the reinforcing screen 190 on which the electrode 182 is patterned is cut into a required size (piece processing). For this reason, in the projected capacitive touch panel device 200, the reinforcing screen 190 is not subjected to the reinforcing process on the cut surface.

  On the other hand, in the projected capacitive touch panel device 100 (see FIG. 3A), the assembly process of the capacitive touch panel 80 and the reinforced screen 90 is as follows.

  That is, first, a large screen is cut into a required size (piece processing). Next, the reinforced screen 90 is obtained by subjecting the screen that has been processed into pieces to a reinforced process. Finally, the completed capacitive touch panel 80 is bonded to the reinforced screen 90 with an adhesive layer 89. Thus, since the capacitive touch panel 80 can be bonded to the reinforced screen 90 with the adhesive layer 89, in the projected capacitive touch panel device 100, the reinforced screen 90 is in a state where the reinforced process is performed on the entire surface.

  Therefore, when the reinforced screen 190 (see FIG. 3B) having the same thickness as the reinforced screen 90 (see FIG. 3A) is used in the projected capacitive touch panel 160, the strength against external pressure is reduced. In order to solve this, it is necessary to use a reinforced screen 190 having the same strength as the reinforced screen 90, but this requires an increase in the thickness h1 of the reinforced screen 190.

  For this reason, in the projected capacitive touch panel device 160, the thickness h2 decreases, but the thickness h1 increases, compared to the projected capacitive touch panel 60. Therefore, the total thickness of the projected capacitive touch panel device 160 (the total thickness of the thicknesses h1 and h2) can be made thinner than that of the projected capacitive touch panel device 60, but the degree is low. there were.

  The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to reduce the thickness of a projected capacitive touch panel.

In order to achieve the above object, a projected capacitive touch panel according to a first aspect of the present invention provides:
A flat screen on which processing for increasing the strength against the external pressure is performed on the entire surface, protecting the display device from external pressure while ensuring the visibility of various information displayed on the display device,
When a dielectric approaches the screen by a plurality of electrodes provided between the screen and the display device in which the first electrodes and the second electrodes are alternately arranged in a matrix, the static due to the approach is obtained. An electrode group that generates a change in capacitance and ensures the visibility of the various information used to identify the position where the dielectric is approached;
A flat film provided between the electrode group and the screen, wherein an adhesive layer is formed on at least one wide surface, and an adhesive layer is formed on the other wide surface facing the one wide surface. An adhesive film that has formed an electrode group and ensures the visibility of the various information;
Protecting the electrode group formed on the adhesive film, ensuring a visibility of the various information,
It has.

  According to the present invention, it is possible to use a screen that has been subjected to a process for increasing the strength against external pressure, and further to eliminate the need for a transparent substrate. Therefore, compared to a conventional projected capacitive touch panel, Thinning can be achieved.

1 is a cross-sectional view of a projected capacitive touch panel device according to an embodiment of the present invention. It is an external view of a projected capacitive touch panel device. (A), (b) is sectional drawing of the conventional projection type capacitive touch panel device.

  Hereinafter, a projected capacitive touch panel device 1 according to an embodiment of the present invention will be described with reference to FIG. In the description of the projected capacitive touch panel device 1, the same reference numerals as those in FIGS. 3A and 3B are used in the projected capacitive touch panel devices 100 and 200. The description is omitted.

  The projected capacitive touch panel device 1 includes a display device 70, a capacitive touch panel 10, and a reinforced screen 90. A combination of the capacitive touch panel 80 and the reinforced screen 90 is referred to as a projected capacitive touch panel 2.

  The capacitive touch panel 10 includes an electrode 11, a film 12, an adhesive layer 13, a wiring 84, a flexible substrate 85, a touch panel driver IC 86, a protective layer 87, and a screen decoration 88.

  The electrode 11 is a transparent electrode that ensures the visibility of various information displayed on the display device 70. The electrode 11 is used for identification by the touch panel driver IC 86 at a position where the finger or the like is approached by generating a capacitance between the finger or the like that is a dielectric when the electrode 11 is approached. The electrode 11 is formed by patterning (printing) ITO on the back surface (surface opposite to the viewing side) of the wide surface of the film 12. This electrode 11 is provided between the reinforced screen 90 and the display device 70, and includes a column electrode 11 (a) extending in one direction (vertical direction) and a column electrode 11 (b) extending in the other direction (horizontal direction). It is composed of a plurality of electrodes arranged alternately and in a matrix. The electrode 11 has the same configuration as the electrode 182 except that the electrode 11 is directly patterned on the back surface of the film 12.

  The film 12 is a flat film provided between the electrode 11 and the screen decoration 88, and the adhesive layer 13 is formed on the at least one wide surface (viewing side surface). The electrode 11 is formed on the other wide surface (surface opposite to the viewing side) opposite to the wide surface. The film 12 ensures the visibility of various information displayed on the display device 70.

  The adhesive layer 13 is a member that bonds the wide surface (viewing side surface) of the film 12 and the reinforcing screen 90 with the screen decoration 88 sandwiched between the reinforcing screen 90. The adhesive layer 13 causes the film 12 to have a screen decoration 88 on a part of the surface of the wide surface, specifically on the peripheral part of the surface. Moreover, the film 12 will be in the state by which the reinforcement | strengthening screen 90 was affixed on the part which the screen decoration 88 of the surface does not exist in the remainder of the surface of a wide surface.

  Next, a rough process for manufacturing the projected capacitive touch panel 2 will be described. In this step, first, the electrode 11 (a) is patterned on the back surface (the surface opposite to the viewing side) of the film 12, and the insulating layer 183 is patterned at a position where the electrode 11 (a) intersects the electrode 11 (b). Then, the electrode 11 (b) is patterned on the back surface of the film 12. Next, the wiring 84 is connected to the electrode 11 (b), and the wiring 84, the electrodes 11 (a) and (b), and the insulating layer 183 are covered with the protective layer 87. A screen decoration 88 is disposed between the surface of the film 12 and the reinforcing screen 90. Finally, the surface of the film 12 and the screen decoration 88 are bonded to the reinforcing screen 90 with the adhesive layer 13.

  In this way, the electrodes 11 (a) and (b) are patterned on the film 12 instead of the reinforcing screen 90 as in the capacitive touch panel 180 (see FIG. 3B). For this reason, in the projected capacitive touch panel 2, the capacitive touch panel 80 (FIG. 3A) in which the film 12 on which the electrodes 11 (a) and (b) are patterned is attached to the reinforced screen 90. Similar manufacturing processes can be performed.

  Thereby, about the reinforced screen 90, what carried out the reinforcement | strengthening process after the piece processing like the shadow type capacitive touch panel 60 (refer Fig.3 (a)) can be used.

  Therefore, in the projected capacitive touch panel 2, the reinforced screen 90 having the same thickness h1 as that of the projected capacitive touch panel 60 (see FIG. 3A) can be used. In other words, the projected capacitive touch panel 2 can use a reinforced screen 90 that is thinner than the projected capacitive touch panel 160 (see FIG. 3B).

  Here, in the projected capacitive touch panel 2, compared with the projected capacitive touch panel 160 (see FIG. 3B), the thickness h2 is increased by the increase in the film 12 and the adhesive layer 13. .

  However, in the projected capacitive touch panel 160 (see FIG. 3B), as described above, the reinforced screen 190 that is not subjected to the reinforced process as a whole must be used. Therefore, in order to achieve the same strength as the reinforced screen 90 in the reinforced screen 190, the thickness h1 of the reinforced screen 190 is increased by the thickness increased by the projected capacitive touch panel 2 (the thickness of the film 12 and the adhesive layer 13). More) than (min).

  Specifically, the increase in the thickness of the projected capacitive touch panel 2 (the thickness of the film 12 and the adhesive layer 13) is in units of μm, whereas the increase in the thickness of the reinforced screen 190 is in units of mm. .

  Accordingly, the thickness of the projected capacitive touch panel 2 (thickness h1 of the reinforced screen 90 + thickness h2 of the capacitive touch panel 10) is equal to the thickness of the projected capacitive touch panel 160 (thickness h1 of the reinforced screen 190 + capacitive touch panel). It becomes thinner than the thickness h2) of 180.

  Further, in the projected capacitive touch panel 2, the electrode 11 is patterned on the back surface of the film 12, and a member for protecting the electrode 11 from heat radiation by the display device 70 is a protective layer 87. Thereby, the electrode 11 can be protected from heat radiation by the display device 70. Therefore, the projected capacitive touch panel 2 can eliminate the need for the transparent substrate 81 (see FIG. 3A). Therefore, the projected capacitive touch panel 2 realizes a reduction in thickness h2 as compared with the projected capacitive touch panel 60 (see FIG. 3A).

  As described above, according to the projected capacitive touch panel device 1 according to the present embodiment, the projected capacitive touch panel 2 can be made thinner than the conventional projected capacitive touch panels 60 and 160. Therefore, the projected capacitive touch panel device 1 can be made thinner than the projected capacitive touch panels 60 and 160.

  More specifically, the film 12 of the projected capacitive touch panel device 1 has a configuration in which a reinforcing screen 90 is pasted on one wide surface and the electrode 11 is formed on the other wide surface facing the one wide surface. It is. With this configuration, in the manufacture of the projected capacitive touch panel 2, it is possible to employ a process of attaching the film 12 on which the electrode 11 is formed to the reinforcing screen 90 (individually the reinforcing screen 90 on which the electrode 11 is formed). The process of one-piece processing can be made unnecessary). Therefore, it is possible to use a reinforced screen 90 in which the entire surface is subjected to a process for increasing the strength against external pressure. Further, a protective layer 87 is provided on the electrode 11 formed on the film 12. Thereby, the electrode 11 can be protected from heat radiation by the display device 70. Therefore, the transparent substrate 81 that is thicker than the protective layer 87 and is conventionally used for protecting the electrode 11 can be eliminated. As described above, according to the projected capacitive touch panel device, it is possible to use the reinforced screen 90 on which processing for increasing the strength against external pressure is performed on the entire surface, and further, it is possible to eliminate the need for the transparent substrate 81. Compared to the conventional projected capacitive touch panels 60 and 160, it is possible to reduce the thickness.

  Further, according to the projected capacitive touch panel device 1 according to the present embodiment, the transparent substrate 81 used in the projected capacitive touch panel device 100 is unnecessary as described above. Therefore, the projected capacitive touch panel 2 can be lighter than the conventional projected capacitive touch panel 60.

  Further, according to the projected capacitive touch panel 2 according to this embodiment, the electrodes 11 (a) and (b) are formed on the film 12. On the other hand, the conventional projected capacitive touch panel 60 has electrodes 82 formed on the transparent substrate 81, and the conventional projected capacitive touch panel 160 has electrodes 182 formed on the reinforced screen 190. . Here, the film 12 used in the projected capacitive touch panel 2 is thinner than the transparent substrate 81 and the reinforced screen 190 even after the electrodes 11 (a) and (b) are formed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible. For example, in the projected capacitive touch panel 2 of the above embodiment, tempered glass is used as the tempered screen 90, but the invention is not limited to this. In the projected capacitive touch panel 2, an acrylic plate may be used instead of tempered glass.

  Moreover, in the said embodiment, although the screen decoration 88 was formed by printing on the back surface (surface on the opposite side to the visual recognition side) of the reinforced screen 90, it is not restricted to this. That is, the screen decoration 88 may be configured by a colored (for example, black) film instead of printing.

  A part or all of the above-described embodiment can be described as in the following supplementary notes, but is not limited thereto.
